I was actually planning for a workation there, and I found that this is actually a great time to visit Mcleodganj. If you are touring there for just a few days, you can avail travel packages for triund trek. I would also recommend the following places...
1. Lam dal lake
2. Ghera Waterfalls
3. Laka Glacier
4. Shepherd's cave
Oct would be good to visit McLeodganj. Visit the Bhagsu Falls and walk upto Shiva cafe. It's a quaint little place up hill. There are innumerable cafe's. You can enjoy sumptuous meal in there. If you want you can trek to Triund also.
